I made the mistake of driving into town today. I forgot that Sunday is when they let all the crazy people drive. It was a strange, annoying trip. I needed some thin, metric bolts. I found what I needed using the sample bolts they have on display. I bought a pack of the same thing, but they weren't the same - M.4-.70 X 30. I don't know why they would be different, but I forced them into the threads, and I cut them short with a Dremel. Hopefully, I'll finish this project tonight while I watch TV.

That is annoying. Mutiple trips just to finish one task are a PITA.

I have noticed that for ages that Sunday drivers seem to be horrible.

Metric and Inch screws and bolts are never interchangeable. I found a few SAE and Metric sockets sizes that are really close. Good luck.

Every metric bolt / nut comes in different thread pitch, like fine, medium and course, in every diameter. So for every bolt you need to know the diameter, length, and thread pitch. Then if you noticed the numbers and figures on the heads indicate the hardness of the metal. Now, if you shop at NAPA, the color of the bols and nuts indicate the pitch of the thread. All that time you spend on your computer, you need to look up the specifications of metric fasteners.

The sample bolt was "M4-.70" and that's what it says on the package I bought (30mm long). Anyway, I cut the bolts and forced them into the threads on the handle. Now the handle is attached. One more thing done. Almost finished. I could drive into town and buy one more thing I need, but I ordered it from Amazon, so I'll wait till Friday. I've become patient in my old age.

I've run into that problem. I know I needed a 10/32 bolt but I didn't realize there were different threads and I brought home the right size bolt with the wrong thread. Bad enough my hobby uses both metric and imperial hardware but I have to worry about thread pitch, too.

"Forcing it" is an accepted practice by craftsmen. Getting a heavier hammer is often the best solution.

I now live less than a mile from a Home Depot! While that make it really easy when I decide to add some mulch to the flower beds or to do a project like toilet repair or replacing a faucet washer, I am glad, though, to see that they are going to be opening an ACE Hardware Store about 7 miles away. ACE - "the helpful place"! Good to have choices.

I decided to spend an hour driving into town and back, looking for something I needed at Joann Fabrics. I had already ordered it from Amazon, but I thought I could buy it there before Amazon's Friday delivery. No choices, no colors, no sizes! Nothing! This is why I shop online.

10/32 is a 3/16 screw or bolt with 32 threads per inch and the threads are considered a fine machine thread. A 10/24 is a 3/16 screw or bolt with 24 threads per inch and is considered a coarse machine thread. Another example is 1/4-20 an 1/4-28. The thread sizes can be found in both screw and bolt configuration. The smaller number will indicate the thread pitch is a coarse thread. The larger number will indicate a finer pitch such as the 32 or 40 as in the threads for the thimble on a micrometer. as the major size goes up the fineness of the threads will also change.

The majority of imperial threads are cut to depth of 75% of the major Diameter, I believe this also holds true for metric. If you have to force a nut or bolt/screw it seems that the depth of cut is something other than 75%. A tap and die set can resolve the issue by recutting the threads

If you take your Dremel and put a thin cut off disc on it then cut 4 slots at the end of the screw it will rethread the hole much better

But because you shop online that is why your local Joann store doesn't stock what you need. It's the chicken or the egg.
